[PATCH] Fix Wundef warning for __cplusplus

[Siddhesh Poyarekar <siddhesh at redhat dot com>]

All current uses of the __cplusplus macro only check if it is defined
or not.  Fix this #if to use $ifdef like the rest of the code.

This fixes the warning on i386.

	* sysdeps/generic/unwind-pe.h: Only check if __cplusplus is
	defined.
